Lynn, oops, forgot to comment on the building - I agree with what Jim said above, if it isn't perfectly square or level or even flat - it is probably more realistic. Don't forget, your talking about a building, a wooden building, that is what 70 something years old? Even if it was "perfect when first built (70 or 50 or 40 or even 30 years ago)", over time things will move, warp, fall off; walls will drop, floors will twist and things will be "rough repaired" and so forth. Bottom line mate is, I like it but if you are going to "fix" what you think is wrong, then I wouldn't try to get it perfect.
